<p>If one or more patterns are given, only refs are shown that
match against at least one pattern, either using fnmatch(3) or
literally, in the latter case matching completely or from the
beginning up to a slash.</p>
</dd>
<dt class="hdlist1">--stdin</dt>
<dd>
<p>If <code>--stdin</code> is supplied, then the list of patterns is read from
standard input instead of from the argument list.</p>
</dd>
<dt class="hdlist1">--count=&lt;count&gt;</dt>
<dd>
<p>By default the command shows all refs that match
<code>&lt;pattern&gt;</code>.  This option makes it stop after showing
that many refs.</p>
</dd>
<dt class="hdlist1">--sort=&lt;key&gt;</dt>
<dd>
<p>A field name to sort on.  Prefix <code>-</code> to sort in
descending order of the value.  When unspecified,
<code>refname</code> is used.  You may use the --sort=&lt;key&gt; option
multiple times, in which case the last key becomes the primary
key.</p>
</dd>
<dt class="hdlist1">--format=&lt;format&gt;</dt>
<dd>
<p>A string that interpolates <code>%(fieldname)</code> from a ref being shown
and the object it points at.  If <code>fieldname</code>
is prefixed with an asterisk (<code>*</code>) and the ref points
at a tag object, use the value for the field in the object
which the tag object refers to (instead of the field in the tag object).
When unspecified, <code>&lt;format&gt;</code> defaults to
<code>%(objectname) SPC %(objecttype) TAB %(refname)</code>.
It also interpolates <code>%%</code> to <code>%</code>, and <code>%xx</code> where <code>xx</code>
are hex digits interpolates to character with hex code
<code>xx</code>; for example <code>%00</code> interpolates to <code>\0</code> (NUL),
<code>%09</code> to <code>\t</code> (TAB) and <code>%0a</code> to <code>\n</code> (LF).</p>
</dd>
<dt class="hdlist1">--color[=&lt;when&gt;]</dt>
<dd>
<p>Respect any colors specified in the <code>--format</code> option. The
<code>&lt;when&gt;</code> field must be one of <code>always</code>, <code>never</code>, or <code>auto</code> (if
<code>&lt;when&gt;</code> is absent, behave as if <code>always</code> was given).</p>

<h2 id="_field_names">FIELD NAMES</h2>
<div class="sectionbody">
<div class="paragraph">
<p>Various values from structured fields in referenced objects can
be used to interpolate into the resulting output, or as sort
keys.</p>
</div>
<div class="paragraph">
<p>For all objects, the following names can be used:</p>
</div>
<div class="dlist">
<dl>
<dt class="hdlist1">refname</dt>
<dd>
<p>The name of the ref (the part after $GIT_DIR/).
For a non-ambiguous short name of the ref append <code>:short</code>.
The option core.warnAmbiguousRefs is used to select the strict
abbreviation mode. If <code>lstrip=&lt;N&gt;</code> (<code>rstrip=&lt;N&gt;</code>) is appended, strips <code>&lt;N&gt;</code>
slash-separated path components from the front (back) of the refname
(e.g. <code>%(refname:lstrip=2)</code> turns <code>refs/tags/foo</code> into <code>foo</code> and
<code>%(refname:rstrip=2)</code> turns <code>refs/tags/foo</code> into <code>refs</code>).
If <code>&lt;N&gt;</code> is a negative number, strip as many path components as
necessary from the specified end to leave <code>-&lt;N&gt;</code> path components
(e.g. <code>%(refname:lstrip=-2)</code> turns
<code>refs/tags/foo</code> into <code>tags/foo</code> and <code>%(refname:rstrip=-1)</code>
turns <code>refs/tags/foo</code> into <code>refs</code>). When the ref does not have
enough components, the result becomes an empty string if
stripping with positive &lt;N&gt;, or it becomes the full refname if
stripping with negative &lt;N&gt;.  Neither is an error.</p>
<div class="paragraph">
<p><code>strip</code> can be used as a synonym to <code>lstrip</code>.</p>
</div>
</dd>
<dt class="hdlist1">objecttype</dt>
<dd>
<p>The type of the object (<code>blob</code>, <code>tree</code>, <code>commit</code>, <code>tag</code>).</p>
</dd>
<dt class="hdlist1">objectsize</dt>
<dd>
<p>The size of the object (the same as <em>git cat-file -s</em> reports).
Append <code>:disk</code> to get the size, in bytes, that the object takes up on
disk. See the note about on-disk sizes in the <code>CAVEATS</code> section below.</p>
</dd>
<dt class="hdlist1">objectname</dt>
<dd>
<p>The object name (aka SHA-1).
For a non-ambiguous abbreviation of the object name append <code>:short</code>.
For an abbreviation of the object name with desired length append
<code>:short=&lt;length&gt;</code>, where the minimum length is MINIMUM_ABBREV. The
length may be exceeded to ensure unique object names.</p>
</dd>
<dt class="hdlist1">deltabase</dt>
<dd>
<p>This expands to the object name of the delta base for the
given object, if it is stored as a delta.  Otherwise it
expands to the null object name (all zeroes).</p>
</dd>
<dt class="hdlist1">upstream</dt>
<dd>
<p>The name of a local ref which can be considered &#8220;upstream&#8221;
from the displayed ref. Respects <code>:short</code>, <code>:lstrip</code> and
<code>:rstrip</code> in the same way as <code>refname</code> above.  Additionally
respects <code>:track</code> to show "[ahead N, behind M]" and
<code>:trackshort</code> to show the terse version: "&gt;" (ahead), "&lt;"
(behind), "&lt;&gt;" (ahead and behind), or "=" (in sync). <code>:track</code>
also prints "[gone]" whenever unknown upstream ref is
encountered. Append <code>:track,nobracket</code> to show tracking
information without brackets (i.e "ahead N, behind M").</p>
<div class="paragraph">
<p>For any remote-tracking branch <code>%(upstream)</code>, <code>%(upstream:remotename)</code>
and <code>%(upstream:remoteref)</code> refer to the name of the remote and the
name of the tracked remote ref, respectively. In other words, the
remote-tracking branch can be updated explicitly and individually by
using the refspec <code>%(upstream:remoteref):%(upstream)</code> to fetch from
<code>%(upstream:remotename)</code>.</p>
</div>
<div class="paragraph">
<p>Has no effect if the ref does not have tracking information associated
with it.  All the options apart from <code>nobracket</code> are mutually exclusive,
but if used together the last option is selected.</p>
</div>
</dd>
<dt class="hdlist1">push</dt>
<dd>
<p>The name of a local ref which represents the <code>@{push}</code>
location for the displayed ref. Respects <code>:short</code>, <code>:lstrip</code>,
<code>:rstrip</code>, <code>:track</code>, <code>:trackshort</code>, <code>:remotename</code>, and <code>:remoteref</code>
options as <code>upstream</code> does. Produces an empty string if no <code>@{push}</code>
ref is configured.</p>
</dd>
<dt class="hdlist1">HEAD</dt>
<dd>
<p><em>*</em> if HEAD matches current ref (the checked out branch), ' '
otherwise.</p>
</dd>
<dt class="hdlist1">color</dt>
<dd>
<p>Change output color. Followed by <code>:&lt;colorname&gt;</code>, where color
names are described under Values in the "CONFIGURATION FILE"
section of <a href="git-config.html">git-config(1)</a>.  For example,
<code>%(color:bold red)</code>.</p>
</dd>
<dt class="hdlist1">align</dt>
<dd>
<p>Left-, middle-, or right-align the content between
%(align:&#8230;&#8203;) and %(end). The "align:" is followed by
<code>width=&lt;width&gt;</code> and <code>position=&lt;position&gt;</code> in any order
separated by a comma, where the <code>&lt;position&gt;</code> is either left,
right or middle, default being left and <code>&lt;width&gt;</code> is the total
length of the content with alignment. For brevity, the
"width=" and/or "position=" prefixes may be omitted, and bare
&lt;width&gt; and &lt;position&gt; used instead.  For instance,
<code>%(align:&lt;width&gt;,&lt;position&gt;)</code>. If the contents length is more
than the width then no alignment is performed. If used with
<code>--quote</code> everything in between %(align:&#8230;&#8203;) and %(end) is
quoted, but if nested then only the topmost level performs
quoting.</p>
</dd>
<dt class="hdlist1">if</dt>
<dd>
<p>Used as %(if)&#8230;&#8203;%(then)&#8230;&#8203;%(end) or
%(if)&#8230;&#8203;%(then)&#8230;&#8203;%(else)&#8230;&#8203;%(end).  If there is an atom with
value or string literal after the %(if) then everything after
the %(then) is printed, else if the %(else) atom is used, then
everything after %(else) is printed. We ignore space when
evaluating the string before %(then), this is useful when we
use the %(HEAD) atom which prints either "*" or " " and we
want to apply the <em>if</em> condition only on the <em>HEAD</em> ref.
Append ":equals=&lt;string&gt;" or ":notequals=&lt;string&gt;" to compare
the value between the %(if:&#8230;&#8203;) and %(then) atoms with the
given string.</p>
</dd>
<dt class="hdlist1">symref</dt>
<dd>
<p>The ref which the given symbolic ref refers to. If not a
symbolic ref, nothing is printed. Respects the <code>:short</code>,
<code>:lstrip</code> and <code>:rstrip</code> options in the same way as <code>refname</code>
above.</p>
</dd>
<dt class="hdlist1">worktreepath</dt>
<dd>
<p>The absolute path to the worktree in which the ref is checked
out, if it is checked out in any linked worktree. Empty string
otherwise.</p>
</dd>
<dt class="hdlist1">ahead-behind:&lt;committish&gt;</dt>
<dd>

<div class="paragraph">
<p>In addition to the above, for commit and tag objects, the header
field names (<code>tree</code>, <code>parent</code>, <code>object</code>, <code>type</code>, and <code>tag</code>) can
be used to specify the value in the header field.
Fields <code>tree</code> and <code>parent</code> can also be used with modifier <code>:short</code> and
<code>:short=&lt;length&gt;</code> just like <code>objectname</code>.</p>
</div>
<div class="paragraph">
<p>For commit and tag objects, the special <code>creatordate</code> and <code>creator</code>
fields will correspond to the appropriate date or name-email-date tuple
from the <code>committer</code> or <code>tagger</code> fields depending on the object type.
These are intended for working on a mix of annotated and lightweight tags.</p>
</div>
<div class="paragraph">
<p>Fields that have name-email-date tuple as its value (<code>author</code>,
<code>committer</code>, and <code>tagger</code>) can be suffixed with <code>name</code>, <code>email</code>,
and <code>date</code> to extract the named component.  For email fields (<code>authoremail</code>,
<code>committeremail</code> and <code>taggeremail</code>), <code>:trim</code> can be appended to get the email
without angle brackets, and <code>:localpart</code> to get the part before the <code>@</code> symbol
out of the trimmed email.</p>

<p>The raw data in an object is <code>raw</code>.</p>
</div>
<div class="dlist">
<dl>
<dt class="hdlist1">raw:size</dt>
<dd>
<p>The raw data size of the object.</p>
</dd>
</dl>
</div>
<div class="paragraph">
<p>Note that <code>--format=%(raw)</code> can not be used with <code>--python</code>, <code>--shell</code>, <code>--tcl</code>,
because such language may not support arbitrary binary data in their string
variable type.</p>
</div>
<div class="paragraph">
<p>The message in a commit or a tag object is <code>contents</code>, from which
<code>contents:&lt;part&gt;</code> can be used to extract various parts out of:</p>
</div>
<div class="dlist">
<dl>
<dt class="hdlist1">contents:size</dt>
<dd>
<p>The size in bytes of the commit or tag message.</p>
</dd>
<dt class="hdlist1">contents:subject</dt>
<dd>
<p>The first paragraph of the message, which typically is a
single line, is taken as the "subject" of the commit or the
tag message.
Instead of <code>contents:subject</code>, field <code>subject</code> can also be used to
obtain same results. <code>:sanitize</code> can be appended to <code>subject</code> for
subject line suitable for filename.</p>
</dd>
<dt class="hdlist1">contents:body</dt>
<dd>
<p>The remainder of the commit or the tag message that follows
the "subject".</p>
</dd>
<dt class="hdlist1">contents:signature</dt>
<dd>
<p>The optional GPG signature of the tag.</p>
</dd>
<dt class="hdlist1">contents:lines=N</dt>
<dd>
<p>The first <code>N</code> lines of the message.</p>
</dd>
</dl>
</div>
<div class="paragraph">
<p>Additionally, the trailers as interpreted by <a href="git-interpret-trailers.html">git-interpret-trailers(1)</a>
are obtained as <code>trailers[:options]</code> (or by using the historical alias
<code>contents:trailers[:options]</code>). For valid [:option] values see <code>trailers</code>
section of <a href="git-log.html">git-log(1)</a>.</p>
</div>
<div class="paragraph">
<p>For sorting purposes, fields with numeric values sort in numeric order
(<code>objectsize</code>, <code>authordate</code>, <code>committerdate</code>, <code>creatordate</code>, <code>taggerdate</code>).
All other fields are used to sort in their byte-value order.</p>
</div>
<div class="paragraph">
<p>There is also an option to sort by versions, this can be done by using
the fieldname <code>version:refname</code> or its alias <code>v:refname</code>.</p>
</div>
<div class="paragraph">
<p>In any case, a field name that refers to a field inapplicable to
the object referred by the ref does not cause an error.  It
returns an empty string instead.</p>
</div>
<div class="paragraph">
<p>As a special case for the date-type fields, you may specify a format for
the date by adding <code>:</code> followed by date format name (see the
values the <code>--date</code> option to <a href="git-rev-list.html">git-rev-list(1)</a> takes).</p>
</div>
<div class="paragraph">
<p>Some atoms like %(align) and %(if) always require a matching %(end).
We call them "opening atoms" and sometimes denote them as %($open).</p>
</div>
<div class="paragraph">
<p>When a scripting language specific quoting is in effect, everything
between a top-level opening atom and its matching %(end) is evaluated
according to the semantics of the opening atom and only its result
from the top-level is quoted.</p>
